JOSEPH HOWARD BURNHAM, OF IPSXVICH, MASSACHUSETTS.

BEATlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 429,114, dated June 3,1890. Application filed February 3, 1890. Serial No. 339,089. (No model.)

To all whom it may concern:

Beitknown that I, JOSEPH HOWARD BURN- HAM, of Ipswich, in the county of Essex and State of Massachusetts, have invented an Improvement in Return Carpet-Beating Machines, of which the following is a specification.

The object of this invention is to provide a carpet-beating machine with two or more independent or separate beating-cylinders of different lengths, so that either one may be revolved While the other is at rest, or may be revolved in opposite directions or at different rates of speed, as desired. By means of two independent beater-cylinders a narrow or stair carpet may be beaten by the short cylinder anda full-width whole carpet by the loo g beating-cylinder, or either cylinder may be rotated, as desired, while the other one is not in use; and also different grades or kinds may be operated upon and beaten more or less at the same time by means of the separate beatingcylinders, therebylessening the time and labor and more completely control- .lingthe operation of beating carpets than by means of the old common single beating-cylinder machines now in use.

Figure 1 represents a front elevation of my improved double beater-cylinder machine. Fig. 2 represents a vertical cross-section of the same. Fig. 3 represents a sectional detail showing attachment of beater-straps to the cylinder, drawn on an enlarged scale. Fig. 4 represents a perspective view of the exhaust suction-fan or dust-blower.

The frame-work A has suitable bearings to support the journals of the revolving cylinders B B, driven by straight or cross belts, as shown in Fig. 1, so as to reverse the movement of either cylinder whenever desired by shipping the belts.

The beater-straps O are composed of indiarubber belting of suitable width, or of straps of leather or other suitable material heretofore employed. The inner ends of the beaterstraps O are firmly secured to the under side of the horizontal strips E, provided with suitable slots or openings into which the ends of the straps or beaters C are inserted, as shown in Fig. 3. Then the said beater-strips E are permanently secured to the said cylinders B B as shown in Fig. 1. These beater-cylinders are inclosed above by a suitable coverD, within one end of which is placed a fanblower F, (shown in Fig. 4,) which carries or drives all the dust and dirt down or into the lower case G, where'it is expelled or removed as desired, and as heretofore in use.

I am aware that two revolving brushes have been employed in a machine for cleaning furs, as shown in the patent to Hosch, No. 286,928, dated October 16, 1883; therefore I disclaim such, as it could not serve the purpose contemplated by my invention.

It will be seen and understood that by means of my reverse beating-cylinders located between the two beds-one at each side of the beating-cylindersa carpet may be beaten and carried nearly through the machine in one direction; then the beater reversed in motion, so as to carry the carpet back through beneath the beating-cylinder in the opposite direction, so as to rebeat the same until perfectly clean, instead of beating it through several times in the same direction, as heretofore, which requires the carpet to be carried back around the machine by hand each time it is rebeaten.

Having thus described my invention, what I claim is A carpet-beating machine having one long beating-cylinder and one short beating-cylinder journaled in the same plane and each provided with straight and cross belts, whereby the said beaters may be rotated in both directions and independent of each other, and arranged between two beds, so that a carpet may be beaten through the machine in one direction and then the rotation reversed and the carpet rebeaten back through the machine again without removal, substantially as described, as and for the purposes set forth.

In testimony whereof I have signed my name to this specification, this 20th day of May, 1887, in the presence of two subscribing witnesses.

JOSEPH HOWVARD BURNHAM.
